Here's this week's San Mateo County housing market read across the ten Mid-Peninsula cities I track: Belmont, Burlingame, Foster City, Hillsborough, Menlo Park, Palo Alto, Redwood City, Redwood Shores, San Carlos, and San Mateo.

Local Market Activity (August 11 – September 10)

The Mid-Peninsula closed 158 homes in the last 30 days — 59 just this week. The typical home sold for $2.46M and went for 105% of asking, so sellers are still getting a premium over list. Redwood City led on volume with 27 single-family closings, while Hillsborough set the ceiling at a $6.50M median; on the condo side, San Mateo was the busiest market.

Single-Family by Price Point

Splitting the 110 single-family sales by price tells the real story. Under $2M: 18 sold at 105% of list in about 34 days. The $2–3M band was the busiest lane — 43 sold at 108% of list in just 17 days. The $3–4.5M tier stayed hot — 35 sold, 108% of list, 18 days. Even $4.5M+ held firm: 14 sold at 106% of list in 14 days. Over-asking isn't just an entry-level story here — it runs all the way up the price ladder.

This Week vs. the 30-Day Pace

Single-family homes are still the engine: 110 sold over the trailing 30 days at roughly 20 days on market and 107% of list. Condos and townhomes are the calmer lane — 48 sold at about 100% of list. The condo average days-on-market (41) is dragged up by a couple of long-sitting units — one sat 111 days — but the median condo took about 32 days, and the ones that closed this week moved even faster (median 19 days). This week's single-family closings skewed a touch higher-priced (a $2.91M median vs. $2.85M over the full 30 days), a mild high-end tilt rather than a real jump.

The Move Math

Here's what today's numbers mean for a move, using current medians and this week's 6.76% 30-year rate. (Payments are principal + interest, 20% down; taxes and insurance are on top.)

Trading up — condo to single-family:

Median condo $1.12M → 20% down, finance 80%: P&I ≈ $5,825/month plus HOA (many condo buyers here are investors paying all cash).
Median single-family $2.85M → P&I ≈ $14,819/month (trade-up buyers today often put 40–50% down or pay all cash given rates and opportunity cost).

That's a monthly gap of about $9,000 in principal and interest between the two.

Downsizing at 55+ — don't forget Prop 19.

If you're 55 or older, Prop 19 lets you carry your existing low property-tax base to your next California home — up to three times, anywhere in the state. On a home you've owned for decades, that can mean keeping a tax bill tied to a $500–700K assessed value instead of today's market price, often saving $20,000+ per year. For many longtime owners, that single rule is what makes downsizing pencil out.

The Macro Corner.

Mortgage rates: The 30-year fixed averaged 6.76% this week (6.71% a week ago, 6.35% a year ago); the 15-year sits at 6.09%.
The Fed: The target range holds at 3.50–3.75%, and the FOMC meets September 15–16 — after a strong jobs report, markets are pricing a real chance the next move is a hike, not a cut.
Inflation: Headline CPI is running about 2.7% year-over-year, with core PCE — the Fed's preferred gauge — near 2.9%.
Wall Street: Stocks were range-bound for a fourth straight week — the Nasdaq edged up ~0.4%, the Dow slipped ~0.2%, and the S&P was roughly flat.
Bottom line: Rates ticked up again and remain above last year, and a rate cut is off the table for now — but tight local supply, not the rate, is what's driving Mid-Peninsula prices.
